User Review: Black Diamond Forearm Trainer
Source: bought it new
Price Paid: $7
Simple and extremely effective!
- Excellent for grip and endurance training
- There really is no downside to this
This simple rubber ring has done more for my forearm strength in one use than weeks of doing 50 full forearm curls. They wear you out very quickly but you can allow some time to recover and then begin again. I personally use it while sitting around the house until I just can't anymore. This is a no maintenance trainer that I regret not buying months ago.
